That looks a little like something I made with my old Erector set. Good thing the wires are all the same color so’s they don’t get mixxed up?
Teamed up to pull many a wire in the old central offices to identify which wire to move to fix a trouble report or move a telephone number to a new location. Of course, nowadays the process has been made obsolete by electronic/virtual switches.
BTW if we'd had a hand in making the wire runs that sloppy, the chief switchman woulda had a hissy fit.
